[Statin therapy and cognition].

Cognitive problems caused by statins have been noted above all in individual patient cases and to some extent also in epidemiological surveys. The connection may also arise from the fact that by lowering cardiovascular disease mortality statins may predispose their users to the development of memory disorders at an older age. In randomized studies statins have generally been found to have neither adverse nor clearly positive effects on cognition. While the effect of statins on cognition can be evaluated as being neutral, the symptoms complained by the patient must always be considered on a case-by-case basis.
